An uplift spring assembly to compensate for hull deflection at a main bearing
of a mooring turret is disclosed. Elastomeric
pads are used to react turret uplift because of their properties of large
deflections and resistance to cold weather. Tie rods
are provided to transmit the uplift loads into the elastomeric pads. The
elastomeric pads react the uplift loads in compression. The
assembly arrangement prevents the elastomeric pads from reacting tension
loads.
L'invention concerne un ensemble de ressort de poussée permettant de compenser la déformation de la coque au niveau du point d'appui principal d'une tourelle d'amarrage. Des coussinets élastomères sont utilisés pour réagir à la poussée de la tourelle grâce à leurs propriétés de grande déformation et de résistance au temps froid. Les barres d'accouplement permettent de transmettre les charges de poussée aux coussinets élastomères qui réagissent aux charges de poussée en compression. L'agencement de l'ensemble empêche que les coussinets élastomères ne soient soumis aux charges de traction.
